How this service works
100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.
Output
Returns a JSON object with a 'success' boolean, a 'result' object containing the computed bond yield (yield-to-maturity as a decimal or percentage), and a 'computation' string with a human-readable description of the calculation performed.
Example use cases
Corporate bond portfolio yield check
“I'm evaluating a corporate bond with a $1,000 face value, trading at $920, paying $60 in coupons each period, and maturing in 8 periods — what's the yield to maturity?”
Government bond discount yield analysis
“Can you calculate the yield on a US Treasury bond with face value $10,000, current price $9,750, coupon of $200, and 20 periods left?”
Bond pricing model for financial model
“I need the yield to maturity for a bond: face value $5,000, price $5,200 (trading at a premium), $150 coupon per period, and 12 periods remaining.”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/financial/bond-yieldWhen to prefer
Choose this endpoint when you need a pure, serverless mathematical computation of bond yield-to-maturity with no external data dependencies — ideal when you already have the bond parameters and need fast, deterministic financial math without connecting to a market data provider or brokerage API.
Side effects
- Missing required fields (face, price, coupon, periods) returns a validation error
- Non-integer 'periods' value causes a schema error
- Price of zero causes a division error in YTM formula
- Negative face or coupon values may produce nonsensical or error results
- Payment failure via x402 micropayment returns a 402 status before computation begins
